In the article, a method and tools for the automatic estimation of the content of chemical elements using a single spectrum of a sample are described. The presence of the elements in the sample is determined by the technique of cross-correlation qualitative analysis, featuring a low probability of false detection and high speed. The content of the detected elements is calculated using the method of emergence and strengthening of spectral lines modified for the use in an automatic mode in modern spectral complexes. The tools need tuning to a certain complex with the help of the results of quantitative spectral analysis obtained using this complex earlier. The tool operating efficiency is demonstrated with the estimation of the content of the elements of the basis of geological powder samples (Si, Ti, Al, Mg, Fe, Ca, Mn) using the spectra obtained with two different spectral complexes.
